The update will only be pushed to the international version

It's only been a few days since we spotted the Windows Phone 7.8 upgrade for Nokia Lumia 800 and 510 on Navifirm, and now another smartphone seems to be waiting for the same update, the Lumia 900.

The folks over at WPCentral report that Nokia is getting ready for a global rollout of Windows Phone 7.8 and the Lumia 900 will be among the first to receive this upgrade.

Windows Phone 7.8 for Nokia Lumia 900 was recently spotted on Navifirm and it looks like the update will go live simultaneously in multiple countries/regions: Baltics, Austria, Belgium, Denmark, Finland, India, Portugal, Spain, Switzerland, European unlocked, Sweden and others.

Keep in mind that the leaked Windows Phone 7.8 update is only available for the international version of Lumia 900. Unfortunately, AT&T Lumia 900 owners will have to wait a bit longer for this upgrade. Stay tuned for more info on the matter.
